Section Leaving drinks
A room can be drink-taken. A room is usually not drink-taken.
Every turn when the player is in a drink-taken room:
let drink-supporter be a random table in the location;
if a drink is not on the drink-supporter:
say "Someone has already snatched the drink you left here.";
now the location is not drink-taken.
Every turn:
repeat with left-behind glass running through drinks:
if the location of the left-behind glass is not the Bar and the location of the left-behind glass is not the location of the player:
now the location of the left-behind glass is drink-taken;
now the left-behind glass is in the bar;
if the left-behind glass is the mix:
remove the mix from play.
